Abstract: The purpose of this study was the scientific justification for obtaining high yields of malting barley of the Grace variety based on the optimal area and mineral level. The objective of the study was to evaluate the change in the completeness of germination, preservation, and survival of plants resulting from mineral nutrition and the nutrition area and to establish the growth, development, and change in the elements of the crop structure and yield depending on the use of mineral fertilizers (N30P30K30, N60P60K60) and nutrition area. Considering the agro-climatic resources of the southeast of the forest-steppe in the Non-Chernozem region and the biological features, the authors developed methods for realizing the productive potential of malting barley of the Grace variety. A two-factor field experiment was set in 2016, 2018, and 2019. Rational doses of mineral fertilizers and seeding rates in the technology of cultivation of multi-row barley are determined. The paper presents the results of studies on the complex effect of the background of mineral nutrition and the area of nutrition on the density, completeness of germination; preservation, survival of plants; elements of the crop structure, and grain yield of malting barley of the Grace variety on leached chernozems of the Republic of Mordovia (Russia). It is established that the highest grain yield (3.84 t/ha) is provided when mineral fertilizers are applied at the rate of N60P60K60 and the seeds are sown at a norm of 5.0 million germinating seeds per ha.
